Panasonic’s Thermoelectric Hot Water Pipes Generate 7.5 Watts Of Power Per Foot.

Panasonic is designing an improved system to generate thermoelectric power by making it more efficient. Thermoelectric power is created via temperature differences – in this case, between the hot and cold water running through your house. Attempts to generate thermoelectric power in the past have been unsuccessful due to the amount of heat lost in the process.

The video pretty much explains how Panasonic’s thermoelectric tubes work. [DigInfo]

Geothermal Power Isn’t As Sexy As Solar Or Wind And That’s Why It May Be The Most Promising

SMU Geothermal Laboratory and Google.org
Enhanced Geothermal SystemsGoogle and SMU recently completed a study to more accurately determine how much energy could be generated using geothermal sources under the US. This is SMU’s Geothermal Laboratory’s third study on the availability geothermal and their results are pretty amazing – the geothermal potential under the US is nearly 3 million megawatts, or 10 times the amount of power produced by coal plants today. Even crazier is that the geothermal energy potential under West Virginia is greater than what the state could generate annually from coal.

Geothermal is kind of the Ugly Betty on the renewable energy scene and much like the fullback in football. Never glamorous, it rarely gets the same attention as cool solar or sleek wind turbines. Non-glamorous Iceland has found a way to harness its geothermal resources and they currently get 53% of their primary energy from the hot stuff – when will we? [TPM]
